The Ministry of Health reported 517 new COVID-19 cases in Singapore as of 12 pm on June 4.
While the vast majority of the new cases are work permit holders residing in foreign worker dormitories.
There were 15 community cases who were asymptomatic, comprising two Singaporeans/Permanent Residents and 13 Work Pass holders. “All 15 cases were close contacts of earlier confirmed cases, and have already been placed on quarantine. They are all asymptomatic, but we had swabbed them to confirm and verify their status,” MOH said.
Out of the 15 cases, 13 (including one Permanent Resident) reside in a shophouse at Veerasamy Road with an earlier confirmed case. Among them, 3 have positive serological test results, which is indicative of past infections. 8 serological tests have come back negative, and 2 results are pending.
The remaining Work Pass holder was a housemate of another earlier confirmed case at Bendemeer Road, and has been quarantined at a government quarantine facility since 30 May. His serological test has come back positive, which is indicative of a past infection.
The remaining Permanent Resident case is a household contact of previously confirmed cases, and has been placed on quarantine since May 7. Epidemiological investigations are ongoing to determine if this is a past infection.
Overall, the number of new cases in the community has increased, from an average of 5 cases per day in the week before, to an average of 6 per day in the past week.
The new infections take the total number of cases in Singapore to 36,922.
